Hi All,

I'm using kernel 2.6.28 with CentOS 5.2. I have a large source base that is normally compiled as a library file (libmodule.a), but sometimes must be build as a loadable kernel module. Now, I have that working ok, however, when the module is built, the resulting Module.symvers file has a problem. Instead of having values beside the function symbols, e.g.

0x706333a8 libmodule_func /module_dir EXPORT_SYMBOL

It has zeros:

0x00000000 libmodule_func /module_dir EXPORT_SYMBOL

Why is this and how can I get it to compile properly?

Other modules cannot be inserted because they cannot find the correct symbol version for the functions they want to use.

Regards,
Brendan

Just some more information, the kernel has been compiled with CONFIG_MODVERSIONS enabled and the CRC number is being added in other modules I'm compiling. I think this could be an issue to do with building the library in the first build step, then creating the module in the second step (rather than doing it all at once).
